DISCUSSION
THE KBDI REMAINS ABOVE CRITICAL FIRE WEATHER THRESHOLDS IN CABO
ROJO AND BELOW THRESHOLDS IN GUANICA AND CAMP SANTIAGO. BREEZY TO
WINDY ENE WINDS WILL CONTINUE BETWEEN 15 TO 25 MPH WITH HIGHER
GUSTS OVER 30 MPH. TODAY, AN ATMOSPHERIC DISTURBANCE WILL MOVE
OVER THE ISLANDS PROMOTING A WET PATTERN OVER VULNERABLE AREAS,
AND IS EXPECTED TO MAINTAIN RH VALUES AT OR SLIGHTLY ABOVE
THRESHOLD VALUES DURING THE DAY. THIS ALONG WITH THE ABOVE
MENTIONED WINDS WILL AGAIN MAINTAIN AT LEAST A LOW FIRE DANGER
RISK. WE URGE PARTNERS TO CONTINUE MONITORING UPDATES DURING THE
MORNING FOR A POSSIBLE HIGH FIRE DANGER RISK.
